HOLDER WITH PULLEY non DRAVJING cun'reins Application filed. January 2, 1931, SerialNo..

in which the pulley is arranged in a cap supporting a hook. The essence of the present invention is comprised in the fact that the cap is provided with angular recesses embracing lateral trunnions of the pulley.

The invention offers the advantage of providing a bearing for. the pulley wheel axle which operates practically without friction losses, this being brought about by the simplest means. In addition to this, a firm support of the pulley inside the holder is assured.

Forms of execution of the subject matter of the present invention are shown by way of example of the appended drawings.

Fig. 1 being a side elevation of one form of construction, and c Fig. 2 a vertical section along the broken line A-B.

Fig. 3 shows a side elevation of the holder after the cap and the pulley wheel have been removed.

Fig. 4-6 are side elevations of three further forms of construction of the holder.

In the form of construction shown in Figs. 1 to 3 the sheet metal holder w is fitted at its lower extremity with a hook b, whilst the upper portion is provided with an opening 0. The pulley d runs inside this opening. order to avoid unnecessary friction, the opening 0 must be of a larger diameter than the outer diameter of the pulley cl. 7

Joined to the holder at is acap e which covers the upper portion ofthe pulley. The joint can be effected in any desired way. In the form of construction as shown by way of example, the cap is on its upper side provided with an aperture through which pro- 7 the holder a which is bent down after the cap hasbeen slipped on.

At its lower edge and on either side the cap is provided with a recess 9 which serves the purpose of providing a bearing for the axle h of the pulley d. The axle and pulley are preferably made in one piece.

With reference to Fig. 1, the notch or retrudes a tongue f of F 1. In a holder with 5062M, and in Germany January .3, 1330.

cess g'is of an angular shape. lar form would also be possible. The angular shape has the advantage of reducing the friction between the axle of the pulley and thecap. The cap prevents the pulley from falling sideways out of the holder; on the other hand, the pulley is freeto run practically without friction, owing to the fact that the pulley doesnot contact with the cap ex- 'cept at its axle.

i With reference to the form of construction shown in Fig. l, the holder 2' is made of wire. The wire is bent over at 70, thus forming a double wire. One end of this double wire forms a hook Z, whilst the other end of the double wire is bent into the shape of a ring m Pressed onto the upper portion of the ring is a cap a, each of the side walls of which is provided with a recess 0 for the pin p of the pulley g. The point where the two ends of the wire 1116600311 also be placed at some other point.

i The form of construction shown in Fig. 5 differs from the form of construction shown in Fig. 4 only in so far as the cap n is open at the upper end and that the ends m of the wire are placed alongside one another in order thus to secure the cap in its position.

The form of construction shown in Fig. 6 also possesses a cap which is open at its upper end. In order to hold the cap, the ends of the wire m are bent slightly outwards.

In the case of any of the forms of construction shown, the hook can be replaced by an eyelet. i i

I claim 7 1 pulley for drawing curtains, a cap, said cap enclosing the upper half of said pulley and being provided with recesses serving as supporting bearings for said holders on the axle of the pulley.

2. In a holder with pulley for drawing curtains, a cap, said'cap enclosing the upper half of said pulley and being provided with notches of angular shape serving as supporting bearings for said holes on the axle of the pulley.

3. In a holder with pulley for drawing curtains, said holder consisting of a wire of which one end forms a hook, the other end A semi-circu forming a ring surrounding said pulley, a cap, said cap being supported by said ring and enclosing the upper half of said pulley and being provided with recesses serving as bearings for the axle of the pulley.

4. In a holder with pulley for drawing curtains, said holder consisting of a wire of which one end forms a hook, the other end forming a ring surrounding said pulley, a cap, said cap being supported by said ring and enclosing the upper half of said pulley and being provided with notches serving. as bearing for the axle of the pulley, said cap being open at its upper end, the ends of the Wire of said ring being partly bent over to secure the cap in position.

5. In a device of the class described, a supporting member, a roller disposed in said supporting member, said roller being provided wit-h lateral trunnions, and a cap member operatively connected with said supporting member and enclosing the upper portion of said roller, said cap member having bearings in the lower extremity thereof embracing said trunnions and constituting supporting means for said cap and supporting memher.

6. In a device of the class described, a porting member, a roller disposed in supporting member, said roller being provided with lateral trunnions, and a cap member operatively connected with said supporting member and enclosing the upper portion 01 said roller, said cap member having bearing notches in the lower edge thereof embracing said trunnions, and resting solely on said trunnions.

7.. In a device of the class described, a supporting member formedof a single length of Wire rebent on itself and having a portion of the wire at the free extremities of the supsaid same spaced apart forming a roller-receiving CIT portion, a roller in said roller receiving portion, said roller having lateral trunnions, and a cap member disposed over the upper half of said roller and having an opening therein with which the extremities of said wire are adapted to be interloc red, said cap member having recesses therein in which the roller trunnions are seated to sustain the weight on said supporting member.

In testimony whereof I have aflixed my signature.
